6 SHEETS-SHEET 6 72 we ni shown as a light Q reac es surface of theforms must be flush with the outer surface of the web of the channels(Figs. 1, 9 and 14c) or with the surfaces of the ends of the flangesthereof (Figs. 3, 10 and 15) it is desirable to secure attaching membersto the sides of the forms instead of forming such members integraltherewith, although my invention does not exclude forms provided withintegrally-formed attaching members. In the present instance the forms 2consist as shown of plane sheet metal channels the ends of which areprovided with flanges 3 bent at right angles thereto for the purpose ofstiffening the same.

Suitably secured to the sides of the forms by riveting; as illustratedor preferably by spot-welding are attaching members shown by way ofexample as Z-irons 4: in- Figs. 1, 2 and 3 and as channels 23 in Figs.l-l and 15, said attaching members being herein after referred togenerically as angle-irons. The lower ends of the -Z-irons extend overthe flanges of the channels 1 in the arrangement shown in Fig. 1 and amember 5 herein channel apertured to receive the headed bolt 6 whichpasses through the web thereof serves as a clamp to temporarily securethe mold members together, a wingnut 7 being shown in the present instance as bolt. In this case the surface of each form is flush with theouter surface of the webs of each channel 1 and here as in every arrangement the ends of each form abut the flanges of its contiguouschannels, whereby a continuous mold is built up by the channels andforms.

If it is desired to construct a wall having a series of pilasters on oneface thereof, one set of channels is reversed as shown in Fig. 2, and insuch case the surface of each'form is flush with the inner ends of theflanges so that the inner surfaces of said. flanges and the innersurface of the webs of said channels constitute portions of the mold forforming the pilasters.

As shown in Fig. 3 both channels may be arranged so that the innersurfaces of their flanges and webs form portions of the mold forconstructing a wall having a series of pilasters on each face thereof.

Various means may be employed for supporting the mold members verticallyfor wall construction. A simple arrangement is shown in Fig. l andconsists essentially of means such as the angle-iron 8 having a flange 8bolted as shown at 9 to the lower ems of each set of theverticallyarranged laterally-spaced channels. Bolts 9' are passedthrough the apertures in the chan nels alcove the section. the wa l tobe ideal as show in to meals from i ceding on .d y e separators {notshown} are then placed threaded to the outer end of said ing flat-slabfloors the porting and specimbetween the upper ends of the two sets ofchannels to hold the latter apart until the first section. of the wallhas been molded.

After the channels have been placed in position and suitably secured inthe manner above described, the forms are arranged between each oair ofadjacent channels with the outer ends of the Z Z-irons extending overthe flanges thereof and the wing-nuts tightened to clamp the mfildumelnbrs together. The mold so constructed is then filled with concrete toform the first section of the wall and after the concrete has set thewing-nuts are loosened, the clamps 5 turned the bolts 6 to release theends of the Ff-irons, the forms taken down and the holts 9 removed. Theforms are then reassembled higher up on the channels to make the moldfor the second section of the wall, the bolts 6 of the lowermost clamppassing through the holes in which the bolts 9 were arranged while thefirst section was being poured, and

said bolts 9 being placed through holes in the channels above the secondsection. This process is repeated until the required height has beenreached.

. In Fig. 7 l have shown how the archplates 10 described in my Lettersratent 1,216,644, February :20, 1.917, may used in conjunction with theplane forms 2 and their 'coiiperating channels to make a mold for-a wallhaving a series pilasters on one face thereof, suitable wire lathingbeing secured if desired to the outer faces of t e pilasters and coveredwith cement or pla for the purpose of ming a wall having air spaces inthe nsnanwell shown manner. In this case the clam member 11 and bolt 12serve to hold e lower edges of the arch plates against the flanges thechan nels l. i In Fig. 8 two sets of said arch plates and channels areused,,each element of one set being opposite corresponding element ofthe other set, whereby mold is formed for a wall having nilasters onboth faces thereof. wire-lathing and ilastei' a wall having two opposedseries of air spaces may be constructed.
